Recall 14V132 affects 4,192 2008-2014 Autocar Acx, Wxll, and Wx vehicles for frozen intake-manifold condensation. ECM calibration is free at authorized Cummins service facilities.
Autocar is recalling 4,192 2008-2014 Acx, Wxll, and Wx vehicles equipped with Cummins Westport ISL G or ISX12 G engines because condensation in the intake manifold can freeze in cold weather and disrupt the pressure sensor. That raises the risk of a vehicle fire or burn injury, and the Autocar dealer repair is free.

What's wrong?
The intake manifold on the 2008-2014 Autocar Acx, Wxll, and Wx routes air into the engine. The intake manifold pressure sensor reads the air pressure in that manifold and sends that signal to the engine controls. The engine uses that reading to manage combustion on vehicles equipped with Cummins Westport Model ISL G or ISX12 G engines.
On affected vehicles, condensation can collect inside the intake manifold. In cold weather, that moisture can freeze and interfere with the pressure sensor's operation. When the sensor reading is blocked or distorted, the engine controls no longer receive the pressure information they expect from the intake system.
There is no warning sign before failure. Do not count on a sound, smell, or dashboard message before the sensor problem affects engine operation.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone near the pipe. Keep people clear of the exhaust area and schedule the ECM calibration soon. Repair is free at any franchised Autocar dealer.
What should I do?
- Check your VIN to confirm your 2008-2014 Autocar Acx, Wxll, or Wx is included in this recall.
- Contact a franchised Autocar dealer or authorized Cummins service facility to schedule the free ECM calibration update that corrects the intake-manifold pressure sensor issue.
- Bring the recall notice if Autocar has mailed one. If not, reference recall number 14V132 when you call.
- Keep people clear of the exhaust pipe until the ECM update is complete.
What happens at the repair
At an authorized Cummins service facility, a technician uploads a new ECM calibration for the Cummins Westport ISL G or ISX12 G engine. The software update is intended to keep frozen condensation in the intake manifold from interfering with the intake manifold pressure sensor. The recall repair is free, with parts and labor covered. The remedy has been available since April 12, 2014, so owners can ask Autocar or the authorized service facility to confirm the campaign and schedule the calibration update.

Frequently asked questions
What is recall 14V132?
Recall 14V132 covers 4,192 2008-2014 Autocar Acx, Wxll, and Wx vehicles with certain Cummins Westport natural-gas engines. Condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor, raising the risk of exhaust flames, vehicle fire, or burn injury.
What should I do if my 2008-2014 Autocar Acx, Wxll, or Wx is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 14V132. If it is, contact Autocar at 1-765-489-5499 or an authorized Cummins service facility and ask for recall A-1402. The repair is a new ECM calibration.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the recall remedy says authorized Cummins service facilities will upload the new ECM calibration free of charge.
What is the safety risk?
The safety risk is fire or burn injury near the exhaust pipe. If the intake manifold pressure sensor operates improperly, the engine system can produce elevated exhaust temperatures or flames from the exhaust pipe. The free repair updates the ECM calibration to address the defect.
When did the recall repair start?
The recall began on April 12, 2014. For an included 2008-2014 Autocar Acx, Wxll, or Wx, an authorized Cummins service facility performs the ECM calibration update free of charge.
